In recent years, in the process of fabricating OLED display panels, the aperture opening (AA Hole) technology is widely used. Specifically, the inventor of the present application finds that, in the manufacturing process of the OLED display screen, the structure assembly provided with the module through hole generally needs to be protected by the protective film, and the protective film often needs to be torn off before the terminal assembling process, so that the through hole of the structure assembly is easily contaminated, and further the subsequent product yield is affected. For example, in the processing procedure of OLED display screen, before customer end dress camera, can carry out multichannel tear film inspection process to OLED rete through-hole, like laminating precision inspection to, can tear the protection film of pasting on heat dissipation module (SCF), lead to AAhole dirty very easily like this, and difficult clean, thereby cause very big difficulty for camera module equipment, and lead to the product yield to receive the influence easily.
In view of this, the present disclosure provides a protection film module, a display module, a method for manufacturing the same, and a heat dissipation module, so as to improve the problem of the protection yield of each structural component in the manufacturing process of a display product.
The technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the drawings in the embodiments of the present application, and it is obvious that the described embodiments are only a part of the embodiments of the present application, and not all of the embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present application.
As shown in fig. 1 to 3, the present application provides a protective film module, which includes a substrate layer 1 and a first adhesion layer 2, as shown in fig. 4, wherein:
a substrate layer 1 configured to cover a structural component 4 of a display product; the structural component 4 comprises a first opening 40 therethrough;
the first adhesive layer 2 is attached to one side surface of the substrate layer 1 facing the structural component 4 and can be peeled relative to the substrate layer 1, and the size of the first adhesive layer 2 is larger than that of the first opening 40 of the structural component 4 and is configured to cover the first opening 40 of the structural component 4.
The protective film module can be attached to the structural component 4 of the display product to protect the structural component 4 of the display product; specifically, the protective film module comprises a substrate layer 1 and a first adhesive layer 2 attached to the substrate layer 1 and used for covering a first opening 40 of the structural component 4, and the first adhesive layer 2 can be peeled relative to the substrate layer 1, so that in a display product manufacturing process, when a film needs to be torn before a terminal assembly process, the substrate layer 1 can be firstly torn, namely, the substrate layer 1 is peeled from the structural component 4 and the first adhesive layer 2, the first adhesive layer 2 is reserved, and the first adhesive layer 2 is peeled from the structural component 4 until the first opening 40 of the structural component 4 needs to be exposed, so that the first opening 40 of the structural component 4 can be effectively prevented from being dirty, and the first opening 40 does not need to be cleaned in subsequent assembly and the yield of an assembled product can be guaranteed.
For example, as shown in fig. 4, the structural component 4 of the display product may include a heat dissipation module 5, where the heat dissipation module 5 is provided with a first opening 40; specifically, the heat dissipation module 5 is used for being attached to the display module, the first opening 40 of the heat dissipation module is used for exposing a display area opening (AA Hole) of the display module, and the first opening 40 and the display area opening (AA Hole) can be used for accommodating and assembling a functional module (such as a camera module). The protective film module provided by the application can protect the heat dissipation module 5; for example, in the manufacturing process of the display module, the protective film module provided by the present application can be attached to one side of the heat dissipation module 5, and then the other side of the heat dissipation module 5 is attached to the display module, and at this time, the protective film module can form protection on one side of the heat dissipation module 5. In an inspection process before assembling the terminal, for example, when inspecting the bonding precision of the first opening 40 and the display area opening (AA Hole) and/or inspecting the appearance of the heat dissipation module 5 and the display module, the substrate layer 1 of the protective film module can be torn off and the first adhesive layer 2 is retained until the camera module is assembled at the first opening 40, and thus, before assembling the camera module, the first adhesive layer 2 always covers the first opening 40, dirt on the first opening 40 and the display area opening (AA Hole) can be avoided, and therefore, before assembling the camera module, the first opening 40 and the display area opening (AA Hole) do not need to be cleaned, and the yield of the assembled product can be ensured.
In this application, 'bonding' and 'adhering' refer to the two being adhered together by a tacky material. By 'attaching' and 'attaching' is meant attaching the two together, including but not limited to attaching the two together with an adhesive material, and attaching the two together in other ways (e.g., electrostatic adsorption).
In some embodiments, as shown in fig. 4, the present application provides a protective film module in which the first adhesive layer 2 is configured to adhere to an edge of the structural component 4 surrounding the first opening 40. That is, when the protective film module is attached to the structural component 4 of the display product, the first adhesive layer 2 completely covers the first opening 40 of the structural component 4 and the edge of the first adhesive layer 2 is bonded to the edge of the structural component 4 surrounding the first opening 40.
As shown in fig. 2 and fig. 3, in some embodiments, the protective film module provided by the present application may further include a second adhesive layer 3, the second adhesive layer 3 and the first adhesive layer 2 are located on the same side of the substrate layer 1, and the second adhesive layer 3 is attached to the substrate layer 1.
Specifically, the second adhesive layer 3 is disposed around the first adhesive layer 2 and configured to cover a portion of the structural assembly 4 except the first opening 40, as shown in fig. 2 to 4, that is, when the protective film module is attached to the structural assembly 4 of the display product, the second adhesive layer 3 is attached to the portion of the structural assembly 4 except the first opening 40.
Specifically, the second adhesive layer 3 and the first adhesive layer 2 are both adhered to the base material layer 1.
Specifically, as shown in fig. 2, a surface of the second adhesive layer 3 facing away from the substrate layer 1 is substantially flush with a surface of the first adhesive layer 2 facing away from the substrate layer 1.
As shown in fig. 2 to 4, the second adhesive layer 3 is located on the same side of the substrate layer 1 as the first adhesive layer 2, and is disposed around the first adhesive layer 2; attach the protection film module on the structure subassembly 4 of showing the product, specifically can include and paste respectively on structure subassembly 4 with the side surface that deviates from substrate layer 1 of second adhesion layer 3 and the side surface that deviates from substrate layer 1 of first adhesion layer 2. The setting of second adhesion layer 3 can avoid because first adhesion layer 2 and substrate layer 1 have the segment difference (first adhesion layer 2 surface and substrate layer 1 surface have the difference in height) and lead to the peripheral laminating bubble area in a relatively large range that appears of first adhesion layer 2 to can make the attached effect of protection film module relatively good.
Certainly, the protective film module provided in the present application may not be provided with the second adhesion layer, as shown in fig. 1, at this time, the protective film module is attached to the structural component of the display product, and specifically, the first adhesion layer 2 may be adhered to the structural component respectively on a side surface of the substrate layer 1 away from the substrate layer and a part of the surface of the substrate layer 1 except for the surface on which the first adhesion layer 2 is disposed. Specifically, at this moment, the thickness of the first adhesion layer 2 can be reduced as much as possible to avoid the large-range attaching bubble area from appearing around the first adhesion layer 2, so that the attaching effect of the protective film module is improved.
As shown in fig. 2 and 3, in some embodiments, there is a gap between the second adhesive layer 3 and the first adhesive layer 2. Like this, can conveniently carry out the preparation of second adhesion layer 3 and first adhesion layer 2 respectively, avoid second adhesion layer 3 and first adhesion layer 2 to appear overlapping.
Specifically, the size of the gap between the second adhesive layer 3 and the first adhesive layer 2 is determined by the actual manufacturing level and accuracy, and in principle, the gap can be designed to be as small as possible.
As shown in fig. 1 and fig. 2, in some embodiments, the first adhesive layer 2 includes, in order in a direction away from the substrate layer 1, a first UV tack-reducing adhesive layer 21, a first protective film layer 22, and a first adhesive layer 23; the first UV tack-reducing adhesive layer 21 is configured to have a smaller tack than the first adhesive layer 23 after being irradiated with ultraviolet light (UV).
Specifically, as shown in fig. 4, in the first adhesive layer 2, the first UV adhesive reduction layer 21 is used for adhering to the substrate layer 1, and the first adhesive layer 23 is used for adhering to the structural component 4 of the display product; after ultraviolet irradiation, the viscosity of first UV visbreaking glue layer 21 is less than the viscosity of first glue layer 23, and at this moment, when tearing substrate layer 1 off from structural component 4, substrate layer 1 can take place to peel off with first UV visbreaking glue layer 21, and first glue layer 23 can not peel off from structural component 4 to first adhesion layer 2 can continue the adhesion on structural component 4 and cover the protection to the first opening 40 of structural component 4.
As shown in fig. 2, in some embodiments, the second adhesive layer 3 sequentially includes a second glue layer 31, a second protective film layer 32, and a third glue layer 33 along a direction away from the substrate layer 1; the third glue layer 33 has a lower viscosity than the second glue layer 31.
Specifically, as shown in fig. 4, in the second adhesive layer 3, the second adhesive layer 31 is used for adhering to the substrate layer 1, and the third adhesive layer 33 is used for adhering to the structural component 4 of the display product; because the viscidity of third glue film 33 is less than the viscidity of second glue film 31, then when tearing substrate layer 1 off from structural component 4, substrate layer 1 can not take place to peel off with second glue film 31, and third glue film 33 can peel off from structural component 4 to second adhesion layer 3 will break away from structural component 4 along with substrate layer 1.
In some embodiments, the tackiness of the first adhesive layer 23 is greater than the tackiness of the third adhesive layer 33 and less than the tackiness of the second adhesive layer 31. In this way, when the substrate layer 1 is torn off from the structural component 4, the second adhesive layer 3 can be more easily separated from the structural component 4 along with the substrate layer 1, and the first adhesive layer 2 is less easily separated from the structural component 4.
In some embodiments, the first UV detackifying adhesive layer 21 has a greater tackiness than the second adhesive layer 31. That is, without being irradiated by ultraviolet light, the viscosity of the first UV tack reducing adhesive layer 21 is greater than that of the second adhesive layer 31, so that the first adhesive layer 2 can be prevented from peeling off from the base material layer 1 before the protective film module is used or before the film tearing operation.
In some embodiments, the viscosity of the first UV tack-reducing adhesive layer 21 may be 700gf/inch to 1500gf/inch, the viscosity of the first adhesive layer 23 may be 50gf/inch to 100gf/inch, the viscosity of the second adhesive layer 31 may be 300gf/inch to 600gf/inch, and the viscosity of the third adhesive layer 33 may be 5gf/inch to 20 gf/inch.
In some embodiments, the material of the third adhesive layer 33 is UV viscosity reducing adhesive.
As shown in fig. 4, the third adhesive layer 33 is used for bonding with the structural assembly 4 of the display product, the material of the third adhesive layer 33 is UV viscosity reducing adhesive, and before the substrate layer 1 is torn off from the structural assembly 4, the ultraviolet light is adopted to irradiate the third adhesive layer 33, so that the viscosity of the third adhesive layer 33 is reduced, and then the third adhesive layer 33 can be easily peeled off from the structural assembly 4, so that the second adhesive layer 3 can be easily separated from the structural assembly 4 along with the substrate layer 1.
In some embodiments, the material of the substrate layer 1 may be a polyester film (PET); the material of the first protective film layer 22 and the second protective film layer 32 may also be polyester film (PET).
Illustratively, the material of the base material layer 1 and the first protective film layer 22 may be a colorless transparent polyester film, and the material of the second protective film layer 32 may be a blue transparent polyester film.
As shown in fig. 4, the substrate layer 1 and the first protective film layer 22 are colorless transparent polyester films, and the first opening 40 of the structural component 4 can be observed through the substrate layer 1 and the first adhesive layer 2, thereby facilitating the inspection of the alignment of the film layer openings and the display area opening (AA Hole) of the structural component 4.
As shown in fig. 4, in some embodiments, substrate layer 1 may include ears 11 beyond the edges of structural component 4.
Specifically, the ear 11 of substrate layer 1 is not equipped with glue film and adhesion layer, thereby can exert pulling force through centre gripping ear 11 and tear substrate layer 1 from structural component 4.
Based on the same inventive concept as the protective film module provided in the embodiment of the present application, the embodiment of the present application further provides a method for manufacturing the protective film module, which includes:
as shown in fig. 1, a first adhesive layer 2 is attached to a surface of a substrate layer 1 facing a structural component 4 of a display product, and the first adhesive layer 2 can be peeled off from the substrate layer 1; wherein the substrate layer 1 is configured to cover a structural assembly of the display product, the structural assembly comprising a first opening therethrough; the first adhesive layer has a size larger than a size of the first opening of the structural component and is configured to cover the first opening of the structural component.
In some embodiments, before attaching the first adhesive layer to a side surface of the substrate layer facing the structural component of the display product, the method may further include:
as shown in fig. 2 and 3, a second adhesive layer 3 is attached to a surface of the substrate layer 1 facing a side of the structural component of the display product; the second adhesive layer 3 is perforated at the first opening of the second adhesive layer 3 near the structural component to form a via 30 in the second adhesive layer 3 exposing the first opening.
Further, set up first adhesion layer at the substrate layer towards the surface of one side of the structure subassembly of showing the product, specifically include:
